Nutrigenomics: Vitamin B3

Posted by Athletigen on Wed, Dec 05, 2018

Your body uses vitamin B3 (also called niacin) to unlock the energy stored in carbohydrates, fats, and proteins. This can have a direct impact on the amount of energy you have during exercise and daily life. Vitamin B3 can also impact your body’s cholesterol levels.

An increased intake of vitamin B3 has been found to increase levels of HDL “good” cholesterol and decrease levels of triglycerides and LDL “bad” cholesterol.

Vitamin B3 is found in whole grains, mushrooms, and most meat products. Vitamin B3 deficiency is rare, but vegans and vegetarians are at higher risk. Symptoms include rashes in the nose and mouth, and diarrhea.

More common is over consumption among individuals who use too many supplements. Symptoms of vitamin B3 overconsumption include headaches, persistent nausea, and potential liver damage if overconsumption persists over many years.

The DGAT2 gene helps your body use vitamin B3 to help control the levels of triglycerides in your blood. Certain variants of this gene are linked to decreased efficiency of this process and an increased requirement of vitamin B3.
